Serial No. 631,688;

. To all whomii may comm?" Be it known that I, HENRY Hnnn, a citizen of the United States, and a resident of Richmond Hill, borough of Queens, in the county of Queens and State of New York, have invented certain new and useful Improvements in VaultLi l1ts, of which the following is a specification.

This invention relates to improvements in vault lights and particularly to that class of vault lights in which the lenses are supported in a frame of reinforced concrete.

. The object of my invention is to provide a new and improved vault light of this kind which is simple in construction; strong and durable, prevents the scaling of the lenses and presents a continuous glass face at the underside of the vault light and which vault light is not expensive.

In the accompanying drawings .in which like letters of reference indicate like parts in all the figures: Figure is a plan view of a section of my vault light. Fig. 2 is an enlarged cross sectional view of the same on the line a 'a: Fig. 1. Fig. 3 is an enlarged detail side view of one of the lenses. Fig. 4 is a similar view of a lens showing a modified construction.

The lenses or glass lights 1 which I use in making my improved vault light are square in shape at the underside and are preferably square in shape at the top. The upper edge of each lens is beveled downward and outward on each edge as shown and then extends down vertically to form a collar 3. From the underside of the collar the sides of the lens are curved inward and downward and then outward toward the bottom so that the bottom area. of the lens is considerably larger than the top area and at the bottom of this concavely curved line 4 there is a vertical shouhier around the entire lens and which forms square. A short distance inward from the edges of the shoulder 5 a square projection 6 is formed on the underside of the lens producing a rabbet 7 along the bottom edges of the lens. The underside of the lens may be hollowed out as indicated in dotted lines at 8 in Fig. 3 or it may he provided with series of prisms as shown at 9 in Fig. A projecting collar or band 10 is fomned around the downwardly and outwardly flan ing part t of the lens at about one half the heig t of the same for a purpose that will be set forth.

In making the'vault light, the lenses 1 are placed upon a series of wooden slats shown in dotted lines at 11 in Fig. 2 in such a manner that the rabbet 7 engages the side edges of these slots and the shoulders 5 of the several lenses are in snug contact both in longitudinal and transverse direction of the vault light. When the vault light is completed and the temporary supporting slats 11 are removed the entire bottom of the vault light will be composed ofglass and no supporting bars or frames or cement will be visible from below, as portions of the lenses extend beneath the cement and the bottom edges of the several lenses are all in close contact along all their edges. Between the several lenses longitudinal and trans--' verse grooves are thus formed which are substantially circular but are flared upward and outward at the top, which flaring is produced by the bevels 2 along the tops of the lenses. A quantity of cement is placed temporary supporting; slats 11 are removed.

The u iner fiarin-" )arts of the cement sun porting rihs extend over the beveled portions 2 at the tops of the lenses which permits the lenses and fact the entire vaultlight to expand and contract without chipping or scaling the lenses. Likewe the edge parts oflthecement ribs extending over the hevels of the lenses cannot chip oi? because the cement, ribs form one solid. hi'unogeneous body of practically the entire depth of the vault light. The central ribs ii) on the lenses extend into the'rein't'orced cement ribs and engage the same assisting in supporting the lenses from the reinforced cement ribs and in preventing any displacement whatever of the lenses in the frame.

Having described my invention what .i claim as new and desire to secure by Letters Patent is i In a vault light, in combination a series ice of lenses which have agreater area at their m', fliii?
